Weird. Total opposite of what I see. Could this have to do with the
type of sound card I use? That the specific sound driver I'm using
somehow makes xmms tickle a bug in the native pthreads?
Anyway, if someone would like to tell me how to extract the right
information from my hanging xmms to help figure out what's wrong, I
can easily reproduce the situation within a couple of minutes. Here's
what I observed with gdb today:
Start xmms, then, after a few seconds of playing, attach gdb:

Detach, let it play a bit, check again:

Detach, and wait. Program hangs, attach gdb:

(This was a song or two later in the playlist, which may be why the
thread numbers have increased...?)
